Automatically Updating Firmware - Symantec 360R - Security Gateway SGS Administration Manual

Automatically updating firmware

LiveUpdate, manually using LiveUpdate, or manually by receiving firmware
from Symantec Technical Support and applying it using the symcftpw tool. By
default, LiveUpdate checks for updates at the end of the Setup Wizard. You may
disable this feature. See the Symantec Gateway Security 300 Series Installation
Guide.
Warning: Performing a manual firmware upgrade with app.bin may overwrite
your configuration settings. Before performing an upgrade, make note of your
settings. Do not use a configuration backup file of older firmware on newer
firmware. LiveUpdate firmware upgrades never overwrite your configuration.
When you apply a firmware upgrade manually or through LiveUpdate, the LEDs
flash in a unique sequence that indicates the progress.
See "LiveUpdate and firmware upgrade LED sequences"
LiveUpdate is a Symantec technology that enables you to automatically keep
your Symantec products up-to-date with the latest revision. You can configure
LiveUpdate to check for updates automatically, or you can manually run
LiveUpdate at any time to check for updates.
Symantec periodically releases firmware updates to ensure the highest level of
security available. Run LiveUpdate as soon as your Symantec Gateway Security
300 Series is connected to the Internet.
See "Running LiveUpdate Now"
When LiveUpdate checks for firmware updates, if a new firmware package is
found, LiveUpdate downloads and begins applying the firmware without
prompting the administrator. During the download and application, the SGMI
displays a message stating that an update is being applied and to wait a few
minutes before attempting to log into the SGMI. Afterwards, the appliance may
restart. When firmware application is complete, a message is logged.
If LiveUpdate checks for firmware updates and none are available (the current
firmware is up-to-date), a message is logged.
All LiveUpdate packages posted by Symantec are tested and validated by
Symantec. These packages do not intentionally overwrite your current
configuration. However, they require an automatic restart of the appliance. To
minimize downtime or interruption to your network connectivity, use the
Preferred Time feature to schedule updates during off hours.
The LiveUpdate functionality provides a fail-safe mechanism for firmware
updates if the appliance becomes non-usable (such as a power outage during the
